Can a Martial Artist perform a Kiai as a part of a Rapid Strike? With the -3 penalty for TbaM, it's even odds of success against a Will-10 target for even the default Martial Artist, and stunning your foe before you punch him dramatically increases the odds of landing a successful punch.

I'm especially curious because I can probably convince Bruno to let me play a minotaur martial artist, and rapid striking a kiai (at an effective skill 13) followed by a horn strike seems fairly effective.
